OIL-WELL PUMPING-RIG.

SPECIFICATION forming part of Letters Patent No. 593,826, dated November 16, 1897.

' Application filed July 19, 1897. Serial No. 645,102. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD D. YATES, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented a new and Improved Oil-Well Pumping-Bi g, of which the following is a specification.

This invention relates to improvements in pumping-rigs for oil-wells; and it primarily has for its object to provide a mechanism of this character which can be easily transported to oil-fields and having the several parts so constructed that the same can be easily and quickly assembled for use or disconnected.

The invention also seeks to provide a pumping-rig having the cranks of the operating: shaft equipped with novel supplemental portions which serve as protections for the said cranks, take up the wear, and effectively avoid the necessity of putting up new cranks shafts after the rig has been in use a short while, as is frequently necessary when the rod-carrying disks are connected directly to the operating-cranks.

Another and essential object of this invention is to provide a pump-rod-actuating disk arranged to receive and secure the rodsfrom any point, either radially or tangentially to the shaft and in such a manner that the danger of their pulling from the disk is reduced to a minimum.

Furthermore, this invention has for its object to provide a driving mechanism of a very n few parts, combined to form a stable and complete structure of a very simple and economical nature, in which the parts are so arranged that the friction is much less than that found in the rigs now in general use and which will positively and effectively serve for the intended purposes.

With other objects in view, which hereinafter will be made clear, the invention consists in a pumping-rig embodying the peculiar combination and novel arrangement of parts such as will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of my improved pu mping-rig. Fig. 2 is a sectional elevation of the same. Fig. 3 is ahorizontal section taken on the line 3 3 of Fig. 2, illustrating the pump-rod disk in detail. Figs. at and 5 are detail views of the pump-rod disk. Fig. 6 is a vertical section taken on the line 6 6 of Fig. 2. Fig. 7 is a detail view of one of the supplemental bearings or sleeves detached, and Fig. 8 is a detail view illustrating the manner of connecting the rods to the disk.

Referring now to the accompanying drawings, in which like numerals indicate similar parts in all the figures,-1 indicates a suitable iron or steel frame anchored in a foundation end, a bevel drive-gear 24, with which meshes a bevel-pinion 25 on the operating-shaft 25. By referring now more particularly to Fig. 6 it will be noticed that the crank portions of the power-shaft 5 are non-circular in cross-see tion, preferably of octagonal shape, as shown. Each crank portion of the shaft is provided with a detachable supplemental bearing in the nature of a sleeve 7, formed of two sections, having internal bearing-faces of a shape to snugly fit thenon-circular crank and having annular rims '7 7 at the upper and lower ends, and a central annular rim 7 ,which form bearings and guide-seats for the pump-rod disks 18, presently referred to. The rims 7 7 7 b have extensions 7, horizontally apertured to receive the clamp-bolts 8 tice each crank portion is preferably made of such length as to accommodate two actuatingrod disks, the central rim of the sleeve forming the upper bearing-guide for the under disk and the lower bearing for the upper disk.

So far as described it will be readily seen that In pracas the loosely-mounted pump-actuating disks tain its full strength. By connecting the sleeves to the shaft in the manner stated they can be quickly and cheaply replaced when required.

i at

The actuating-disks 18, which are loosely held on the crank-sleeves, consist each of two sections having ribs 18 to receive the clampbolts and provided with a series of dovetail sockets 21 at the periphery, an outer series of bolt-apertures 22, and an inner series of apertures 23.

By referring now to Fig. 3 it will be noticed that the several sockets 21 and the two series of bolt-apertures are so arranged relatively that while each one of the outer apertures can be utilized to secure the rod 24 in but one of its adjusted positions each one of the inner apertures is employed to connect the said rod in two of its adjusted positions, such arrangement of bolt-apertu res being also provided to admit of the rod being secured to the disk at different angles to the axis of the disk, the several sockets 21 being alternately so disposed that the rods can be connected thereto in any direction from the shaft.

By providing the disks with dovetail sockets and making the head of the rods with a dovetail (see Fig. 3) it will be impossible for the rods to pull out from the disk, the bolts 28 holding them down on the disk. Furthermore, by providing the disk with a double series of bolt-apertures, arranged as shown, the rod can be readily secured to the disk in different directions with the use of but half as many apertures for the inner series as is in the outer series.

From the foregoing description, taken in connection with the drawings, it will be readily seen that the power-shaft has no frictional contact whatever with the actuating-disks, as the same have their vertical and horizontal bearings entirely on the sleeves '7 and rims 7 7 thereof. Thus it is manifest that the only part to replace in case of wear are the sleeves 7, which can be cheaply made, thereby saving the crank-shaft, which is the most costly part of the operating mechanism.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-

1. In a pumping mechanism as specified,the combination with the crank-shaft and means for operating the same, of the actuating-disk having annularly-arranged sockets arranged in a series, said sockets having one side thereof in a radial line of the disk, the other side at an inclination to the said radius as set forth.

2. In a pumping mechanism as specified,the combination with the crank-shaft, of an actuating-disk having a series of sockets at the periphery, an outer series of bolt-apertures, one for each socket, an inner series of bolt-apertures, one for each pair of adjacent sockets and a pump-rod having a pair of bolts to engage the inner and outer bolt-apertures substantially as shown and for the purposes described.

3. In an oil-well pumping mechanism, the combination with the supporting-frame, the crank-shaft journaled thereon, means for operating such shaft, said shaft having its crank portion made non-circular, a sectional sleeve fitted on such crank portion,said sleeve having two or more vertical exterior bearings, a horizontal bearing intermediate the vertical bearings, and upper and lower horizontal bearings, a sectional actuating-disk mounted on such horizontal and vertical sleeve-bearings, said disk having a series of alternately radially disposed dovetail sockets, a bolt-aperture in each socket, a bolt-aperture at a point intermediate the inner end of each pair of sockets, of a pump-rod having a dovetail head to engage the sockets and a pair of bolts to engage the bolt-apertures, all being arranged substantially as shown and for the purposes described.
